DFW-bound flights are the slower direction by about 80 minutes in our estimate: the route runs mostly east–west through latitudes where the prevailing westerly winds at cruise height are strong, so heading east rides a tailwind and heading west fights a headwind. How we estimate it.
| Great-circle distance | 7,627 km · 4,739 mi · 4,118 nmi |
|---|---|
| Initial heading | 42° (NE) from DFW; 296° (WNW) from LHR |
| Farthest from the equator | 56.1°N — the path arcs north of both airports |
| Crosses | neither the equator nor the 180th meridian |
| Share of the longest possible trip | 38% of the 20,015 km to the far side of the Earth |
| DFW | America/Chicago — UTC−5 now; UTC−6 standard time, UTC−5 during daylight saving time |
|---|---|
| LHR | Europe/London — UTC+0 now; UTC+0 standard time, UTC+1 during daylight saving time |
| Difference | London is 5 hours ahead of Dallas–Fort Worth today. |
Jet lag, flying DFW → LHR. Your body clock has to move 5 hours earlier, like an eastward trip. A common rule of thumb is that the body clock adjusts by roughly one time zone a day, so expect up to about 5 days to fully adjust. Shifting earlier (as here) is usually the harder direction; morning daylight at the destination helps. Flying the other way, the shift is reversed.
